BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. FIG. 1 is a block diagram showing an embodiment of the present invention.

The automatic monitoring means 1 automatically selects a monitoring screen corresponding to a preset plant state based on process data sequentially input from the plant and outputs a display request. The display request is automatically monitored. It is input to the screen management device 2. The automatic monitoring screen management device 2 manages the monitoring screens to be displayed on the display device 3 when the automatic monitoring means 1 makes a duplicate request to display the monitoring screens. The monitoring screen to be displayed on the monitoring screen is determined according to the priority, and another overlapping monitoring screen is put on display.

The automatic monitor screen management device 2 is a display device based on a screen information database 4 for storing screen information of monitor screens prepared in advance and the priority of monitor screens requested to be displayed by the automatic monitor means 1. 3, a control unit for switching the display of the monitoring screen and waiting for display, a screen number storage unit 6 for storing the number of monitoring screens waiting to be displayed on the display device 3 among the monitoring screens requested to be displayed, and a display waiting unit. And a screen information storage unit 7 for extracting and storing the screen information of the monitoring screen from the screen information database 4.

Further, the control unit 5 of the automatic monitoring screen management device 2
Has input determination means 8 for determining the presence or absence of the automatic monitoring stop signal S1 when a display request is issued from the automatic monitoring means 1. The input determination means 8 determines, based on the automatic monitoring stop signal S1, whether or not it is permitted to display a predetermined monitoring screen on the display device 3 in response to a change in the state of the plant. When S1 is present, even if there is a display request from the automatic monitoring means 1, the automatic monitoring screen is not displayed on the display device 3. On the other hand, when there is no automatic monitoring stop signal S1, the control processing means 9 is activated. Further, a screen display request signal S2 from the operator is input to the input determination means 8, and a screen display process is performed to display and output an automatic monitoring screen, which will be described later, on the display device 3 based on the screen display request signal S2. The means 10 is activated.

Here, in the display request of the automatic monitoring screen from the automatic monitoring means 1, the screen number is input as an identifier uniquely showing the monitoring screen. When activated by the input determination means 9, the control processing means 9 retrieves screen information corresponding to the screen number designated by the automatic monitoring screen display request from the automatic monitoring means 1 from the screen information database 4 and requests the display. The priority of the monitor screen that had the error is determined. Then, when the priority is equal to or higher than the predetermined priority (when the priority is high), the display of the monitoring screen on the display device 3 is switched. On the other hand, when the priority is lower than the predetermined priority (when the priority is low), the display waits.

For example, as the priority, "0", "1",
If the priority of the read screen number is "2", the three screens of "2" are prepared in advance, and the monitor screen is updated and displayed on the display device 3 without waiting for display. Also,
When it is less than or equal to "1", that is, less than "2", the number of screens in the screen number storage unit 6 is increased by 1 and the screen information of the monitor screen in the display wait state is stored in the screen information storage unit 7. As a result, the screen information of the automatic monitoring screen that is waiting to be displayed is displayed on the screen information database 4 by the control processing means 9.
And is stored in the screen information storage unit 7.

Then, the control processing means 9 displays a waiting information area on a part of the monitoring screen being displayed on the display device 3, and displays the number of monitoring screens waiting to be displayed in the waiting information area.
This waiting information area is displayed by, for example, an icon. As a result, the icon displayed in this waiting information area displays the number of automatic monitoring screens if the number of screens in the screen number storage unit 6 is 1 or more. Can be notified.

When a display request for an automatic monitoring screen waiting for display is made by an operator while the monitoring screen waiting for display is present, the screen display processing means 10 displays the monitoring screen waiting for display on the display device 3. Perform processing to In this case, the monitor screens that are waiting to be displayed are displayed from the latest one.
Since the number of monitor screens waiting to be displayed decreases by 1 because the automatic monitor screens waiting to display are displayed on the display device 3, the number of screens in the wait information area is reduced by 1 to be updated.

The background color processing means 11 determines the background color of the monitor screen displayed on the display device 3 based on the number of screens stored in the screen number storage unit 6, and the number of monitor screens waiting for display. Is made intuitive by the background color. That is, the background color of the display device 3 is changed according to the number of screens in the screen number storage unit 6 to notify the user that there is an automatic monitoring screen and the approximate number of screen information stored in the screen information storage unit 7. To notify.

The erasing processing means 12 is for erasing the screen information of the monitor screen waiting for display stored in the screen information storage section 6 based on the condition for erasing the monitor screen waiting for display. As will be described later, is automatically deleted when a predetermined time has elapsed from the start time of display waiting.

FIG. 2 is a flowchart showing the processing contents of the control unit 5. The input determination means 8 uses the automatic monitoring stop signal S
1 is determined (S1), and when there is a request to stop the function of the automatic monitoring means 1, since the display of the automatic monitoring screen on the display device 3 is prohibited, the automatic monitoring screen management device 2 Terminate the function.

On the other hand, when there is no automatic monitoring stop signal S1, it is judged whether or not there is a request for displaying an automatic monitoring screen from the automatic monitoring means 1 (S2). Then, when there is a request to display the automatic monitoring screen, the control processing means 9 is activated to execute the control processing function (S3), and then the erasing processing means 12 is executed (S4). That is, the monitor screen having a high priority is updated on the display device 3, and the monitor screen having a low priority is displayed. In that case, an icon indicates that there is a monitor screen waiting to be displayed in a part of the wait information area of the monitor screen being displayed. After that, an automatic monitoring screen that satisfies the deletion condition is determined from among the automatic monitoring screens waiting to be displayed, and if there is an automatic monitoring screen that satisfies the deletion condition, the automatic monitoring screen is deleted.

If it is determined in step S2 that there is no request to display the automatic monitoring screen, it is determined whether or not the operator has the screen display request signal S2 (S5). Then, if there is a screen display request signal S2 from the operator via the display device 3, the screen display processing function of the screen display processing means 10 is executed to display the automatic monitoring screen waiting for display on the display device 3. Also in this case, after the processing, the erasing processing means 12 is activated to execute the erasing processing function (S4). That is, an automatic monitoring screen that satisfies the deletion condition is determined from among the automatic monitoring screens waiting to be displayed, and if there is an automatic monitoring screen that satisfies the deletion condition, the automatic monitoring screen is deleted.

Next, FIG. 3 is a flow chart showing the processing contents of the control processing means 9 of the control unit 5. Control processing means 9
When there is a request to display the automatic monitoring screen from the automatic monitoring means 1, the display request is input and the time when the display request is made is stored as the display request generation time (S1). Then, the screen number is fetched from the display request, and the screen attribute data of the screen information corresponding to the screen number is fetched from the screen information database 4 (S2). The screen attribute data is shown in FIG.
Screen number, screen priority, screen title,
It consists of the time until deletion and the display color.

That is, the screen priority is divided into three levels of "0", "1", and "2" corresponding to the screen number, and the priority "2" is the highest priority of the screen level,
"0" indicates the lowest priority. Further, the screen title is used when notifying that there is a monitor screen waiting to be displayed in the waiting information area, and the time until erasing is used when determining whether or not the erasing processing means 12 erasing condition is satisfied as described later. Used for. In addition, the display color determines the display color for the waiting information area, and that display color has priority (importance).
It can be changed and displayed.

When the screen attribute data is input from the screen database, the control processing means 9 determines the priority of the screen number requested to be displayed. Then, it is determined whether or not the priority is "2" (S3), and if the priority is "2", the monitoring screen is displayed on the display device 3 (S4).

On the other hand, when the screen priority is less than "2",
The erase time is calculated from the sum of the stored occurrence time and the time until the screen attribute data is erased (S5). Then, the display color of the screen attribute data is set to the icon display color, and the screen title is set to the icon title (S6). In addition, 1 is added to the number of screens stored in the number-of-screens storage unit 6 to update the number of screens (S7), and the screen information of the screen number requested to be displayed is stored in the screen information storage unit 7 (S8). ). That is, the erase time calculated in step S5 is stored in the screen information storage unit 7.

After that, the background color processing means 11 is activated to set the background color of the monitor screen displayed on the display device 3 (S9). The background color processing means 11 determines the background color based on the number of monitor screens waiting to be displayed. Then, the display of the icon is requested in the waiting information area on the monitor screen (S1).
0).

FIG. 5 is a flowchart showing the processing contents of the background color processing means 11. In the background color processing means 11,
The background color of the display device 3 is determined from the number of screens in the screen number storage unit 6 by the following procedure. First, black is stored in the variable ICOLOR, and the number of screens in the screen number storage unit 6 is stored in the variable INUM (S1). Then, it is determined whether the variable INUM (the number of screens) is a first predetermined number (for example, 5) or less, and if the variable INUM is the first predetermined number of 5 or less, the variable IC
Yellow is stored in OLOR (S3). Then, the background color is displayed in yellow (S4).

The variable INUM is determined to be the first by the determination in step S2.
When the predetermined number exceeds 5, the second predetermined number is determined to be 10 or less (S5). If the variable INUM is 6 or more and 10 or less, orange is stored in the variable ICOLOR (S6). ). Then, the background color is displayed in orange (S4).

In addition, the variable INUM is determined in step S5.
Is greater than the second predetermined number of 10, it is determined whether the third predetermined number is 15 or less (S7), and the variable IN
If UM is 10 or more and 15 or less, red is stored in the variable ICOLOR (S8). Then, the background color is displayed in red (S4).

Then, in the determination of step S7, the variable INU
When it is determined that M exceeds 15, the variable ICOLO
White color is stored in M (S9), and the white color stored in the variable ICOLOR is displayed as the background color of the display device 3 (S9).
4).

FIG. 6 is a flowchart showing the processing contents of the erasing processing means 12. In this erasing processing means 12,
The automatic monitoring screen stored in the screen information storage unit 7 is searched for the screen at the deletion time, which is deleted from the screen information storage unit 7 and the number of screens in the screen number storage unit 6 is reduced. Also,
The background color of the display device 3 is reset and the notification icon is reset.

In FIG. 6, the current time is set in the variable CTIME, the number of screens is set in the variable INUM and the variable GNUM, and
Further, "-1" is set to the variable I (S1). Variable IN
It is determined whether or not UM is 0 or less. If it is 0 or less, there is no monitor screen waiting for display, and the process is terminated (S
2). When the variable INUM is 1 or more, the variable I is 1
Is added (S3), and the updated variable I and variable INUM are compared (S4).

Now, assuming that the number of screens is 3, the variable IN
Since UM is 3 and variable I is 0, variable I is smaller. Therefore, the process proceeds to step S5. In step S5, the erase time of the I-th, that is, the 0-th screen information stored in the screen information storage unit 7 is taken out and stored in the variable DTIM. Then, the variable CTIME storing the current time is compared with the variable DTIME storing the erase time of the 0th screen information (S6), and when the erase time coincides, the screen information is erased and 1 is subtracted from the variable GNUM. Then step S3
Return to (S7). On the other hand, when the current time does not match the erase time, the process directly returns to step S3. Similarly, the number of screens (variable INUM) is repeated in steps S3 to S7.
The process of is repeated.

When the processes of steps S3 to S7 are repeated by the number of screens set in the variable INUM, the variable I becomes equal to or more than the variable INUM in the determination of step S4, and therefore the process proceeds to step S8. In step S8, it is determined whether or not there is erased screen information. If there is no erased screen information, the process ends, and the process returns to the start after a predetermined time limit. On the other hand, if there is erased screen information, the erased portion of the year information storage unit 7 is closed (S
9), the number of screens in the screen number storage unit 6 is set in the variable GNUM (S10).

Next, the background color processing means 12 is activated to set the background color of the monitor screen displayed on the display device 3 (S1).
1). Then, by referring to the th screen information stored in the variable GNUM, the icon display color is determined and the screen title is determined (S12), and the display update of the icon is requested to the waiting information area on the monitoring screen (S13). . That is, when there is screen information erased by the erasing means 12, the icon display in the waiting information area is also updated.

FIG. 7 shows the screen display processing means 10 of the control unit 5.
5 is a flowchart showing the processing contents of FIG. The screen display processing means 10 starts the process in response to the operator screen display request signal S2 from the display device 3. In that case, the latest automatic monitoring screen stored in the screen information storage unit 7 is taken out (S1),
The retrieved automatic monitoring screen is displayed on the display device 3 (S2). That is, the last automatic monitoring screen in the screen number storage unit 6 is displayed. Then, since it is no longer the monitoring screen waiting for display, the screen information of the displayed automatic monitoring screen is deleted from the screen information storage unit 7 (S3).
Further, the number of screens in the screen number storage unit 6 is decremented by 1 (S4), the background color processing means 12 is activated, and the background color of the monitor screen displayed on the display device 3 is set (S5). Further, the icon display color is determined and the screen title is determined (S6), and the display update of the icon is requested to the waiting information area on the monitoring screen (S7). That is, when there is screen information erased by the erasing means 12, the icon display in the waiting information area is also updated.

Next, the waiting information area on the monitor screen will be described. FIG. 8 shows a case where an icon is displayed when notifying that there is an automatic monitoring screen waiting to be displayed in the waiting information area on the monitoring screen. The icon 13 is displayed on the monitor screen displayed on the display device 3 when the automatic monitor screen is waiting to be displayed. If there are multiple automatic monitoring screens, the latest one is displayed over the old one.

The display position is one of the four corners of the display device 3. In general, the monitor screen displayed on the display device 3 tends to be designed so that the corner of the screen is not used as much as possible for the convenience of viewing and operation. Therefore, even if the icon 13 is displayed in the corner, important information is hardly hidden. Therefore, the possibility of hiding important information in the four corners of the display device 3 is reduced.

The icon 13 displays the number of screens waiting to be displayed. The figure shows the case where two automatic monitoring screens are waiting to be displayed. It is also effective to blink (blink) the icon 13 or make a sound, or to use these in combination to draw the attention of the operator.

To display the automatic monitoring screen, move the cursor to the icon 13 and press a pointing device button such as a mouse or a tracker ball.
Do by clicking. In this case, when the display device 3 has a touch screen, the automatic monitoring screen is displayed by pressing the icon 13 with a finger.

In FIG. 9A, the notification of the automatic monitoring screen is displayed in a small notification screen 14 for the waiting information area on the monitoring screen.
It shows what was done in. The notification screen 14 is displayed on the monitoring screen displayed on the display device 3 when the automatic monitoring screen is waiting to be displayed. Similar to the case of FIG.
If there are multiple automatic monitoring screens waiting to be displayed, the latest one is displayed over the old one. The display position is set at any of the four corners of the display device 3.

On the notification screen 14, as shown in FIG. 9B, the number of screens waiting to be displayed and the screen title are displayed. In this case, the notification screen 14 to draw the attention of the operator
It is also possible to blink (blink), make a sound, or use together. Further, when the automatic monitoring screen is displayed, the cursor is moved to the notification screen and the button of the pointing device such as the mouse or the tracker ball is pressed and clicked. If the display device 3 has a touch screen (input device from the screen), the automatic monitoring screen is displayed by directly pressing the notification screen 14 with a finger.

In the above description, the latest one is displayed on top of the old one, but the predetermined number is displayed without being overlaid, and when the predetermined number is exceeded, the newest one is displayed. Is also good. Alternatively, the priority may be displayed in a superimposed manner. For example, the priority "1" and the priority "0" may be displayed separately, and the latest one may be displayed over the old one.

As described above, when the automatic monitoring screen is displayed according to the operator's request, since the automatic monitoring screen (display request) stored last as the display wait is displayed, the latest automatic monitoring screen can be displayed.

[0065]

As described above, according to the plant monitoring control apparatus of the present invention, even when a request for displaying the automatic monitoring screen is generated due to a change in the plant state while monitoring the monitoring screen, the monitoring currently being displayed is performed. It can notify the occurrence of the automatic monitoring screen without disturbing the screen display. Further, since it is possible to make a request to display the automatic monitoring screen that has been waiting for display, the automatic monitoring screen that has been waiting for display can be easily displayed.

When an important monitoring screen having a high priority is automatically monitored, the screen is displayed without making a display request, so that the important automatic monitoring screen can be displayed with priority. Become
